Music

"I once had an employee who listened to her iPod while she was working," Teach says. "We worked with a lot of numbers and there was no room for error. I wondered how she could possibly have 100% accuracy with her work when music was pulsating between her ears. I understand that listening to music makes the day go faster and makes the work more enjoyable but given the potential for error when listening to music, the simple solution is not to listen to music, at least directly in your ears."
